Marriage?

This may be stupid but I'll ask anyway. I married Alex in the "till death do us part" quest. and bought a house. later she said she hated the house and if I don't buy her a new one she would leave. So I bought the "Nice house" and the game acted as if I was marrying her for the first time. our "child" is in the old house still and I can't rent it out. Now I'm paying two upkeep prices. Can anyone help? What should I do?6 years ago
